Abstract
A system and method for repairing soft tissue comprises introducing an instrument having a shaft into an operative site, such as a human shoulder. Then, a flexible grasper is advanced from the instrument to capture a portion of soft tissue. The flexible grasper is then retracted so that the captured tissue lies in a pathway for a needle in the instrument. The needle is advanced along the pathway through the captured tissue, and then a portion of suture is captured with the needle, distally of the captured tissue. The needle is retracted proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue. The plicated tissue is then released from the grasper.
Claims25
A system for transdermal repair of soft tissue, said system including an instrument comprising:
- an instrument shaft having an axis;
- a flexible grasper disposed within said instrument shaft and being capable of advancing and retracting in a generally axial direction;
- a suture source;
- and
- a needle disposed within said instrument shaft which is capable of advancing and retracting in a generally axial direction.
A system for transdermal repair of soft tissue, comprising:
- an instrument having a shaft, said instrument having an axis;
- a needle disposed on said instrument and being capable of advancement and retraction in a generally axial direction;
- and
- a needle support tube which is capable of advancing and retracting in coordination with said needle.
A method of repairing soft tissue, comprising:
- introducing an instrument having a shaft into an operative site;
- advancing a flexible grasping device distally from said instrument to capture a portion of soft tissue;
- retracting said flexible grasping device so that the captured tissue lies in a pathway for a needle in said instrument;
- advancing the needle along said pathway through the captured tissue;
- capturing a portion of suture with said needle, distally of said captured tissue;
- retracting the needle proximally through the captured tissue, to thereby pass the suture therethrough and plicate the tissue;
- and
- releasing the plicated tissue from said grasper.
